Don’t forget to add a .json extension into the file name.

The simplest way to write code for your token is to copy the example below. Just copy-paste the code below and edit by entering your token parameters. Replace YOUC with your token symbol, enter your token smart contract address, decimals, and so on.

{
  "symbol": "YOUC",
  "address": "0x3D371413dd5489F3A04C07c0C2CE369c20986ceb",
  "decimals": 10,
  "name": "yOUcash",

  "ens_address": "",
  "website": "https://youengine.io",
  "logo": {
    "src": "https://i.ibb.co/jV6Ymn4/youc-lolo-square-128x128.png",
    "width": "128",
    "height": "128",
    "ipfs_hash": ""
  },
  "support": {
    "email": "info@youengine.io",
    "url": "https://youengine.io"
  },
  "social": {
    "blog": "",
    "chat": "",

    "twitter": "https://twitter.com/younive87630435",
    "youtube": "https://www.youtube.com/c/YOUengine"
  }
}

Note that the required parameters that you must include in the code are:

  • symbol: Short ticker-style symbol of your token.
  • name: long token name token (take it from Ethercsan).
  • address: Ethereum address of ERC-20 token, but in ERC-55 format
  • decimals: The decimals of the token. As a Number and not a String.

Optional parameters are the following:

  • logo: An optional logo of your token. Must be a square (recommended: 128×128) PNG w/ transparent background.
  • support: A support email, support URL, or other way people can get assistance regarding the token.
  • website: the link to your project website, and
  • other links to your project’s social accounts.

We suggest you include as many as possible parameters.

Step 6. Check and confirm

After you entered the file name and code (as on the picture above), scroll down and click on ‘Propose new file’

Step 7. Create a pull request

Confirm your submission two times, as shown below. Also, you can add a comment like “Add [your token name] token.” As a result, you create a Pull Request.

Step 8. Wait for checking

If you successfully created the file (without any errors) then you see the status of your Pull request as verified (colored green on the picture below).

Note that your request will require additional checking. Trezor’s authorized team will do it. Your need just to wait to pass it.

Also, you can check the status of your request in this folder.
The gray color means that the request is under checking. A green checkmark indicates that Pull Request has successfully passed Trezor checking.

Trezor team will review your issue and give feedback. They will confirm if they would like to add your token in the firmware. Otherwise, they will decline. Please note that they can not merge each and every token.

When your Pull Request successfully passes all checking, you see it in this section. It means that Pull Requests merged into the Master. After that, just wait for the next Trezor firmware update to see your token in the List.

Moreover, Trezor allows making secure payments without exposing your private keys to a potentially compromised computer.

Nowadays, many online exchanges and wallet providers can be hacked or just disappear. So, a hardware wallet like a Trezor is the safest way to manage cryptocurrencies.

What’s the List of coins & tokens supported by Trezor?

The list of coins and tokens supported by Trezor is a list of cryptocurrencies. There are more than 1631 coins and tokens on the list right now.

So, if a crypto asset is on that list then Trezor’s users can search it by using name and symbol. If your token is not in the list, then Trezor’s users have to use a smart contract address to find your token.

Fortunately, your token doesn’t have to be a Top 30 cryptocurrency to be added to the list. Also, you don’t have to pay to be added.

What are the benefits of being on Trezor’s List?

The first benefit that you get is a promotion. After adding your token to the Trezor list of coins, you can publish great news. That achievement can inspire your project’s community.

The second benefit is the growth of trust among the holders of your token. Especially it might be necessary for new big buyers of your coins.

Finally, all Trezor users can easily search for your token inside the wallet by using just its name or symbol. Users can also see your token’s logo inside the Trezor interface.

So what’re you waiting for? Add your ERC20 token to the List of coins & tokens supported by Trezor for free. It’ll make your token a much more reliable and attractive asset for all existing and potential token-holders.
